I was recently asked, "Does anyone know why vampires have 'leaky energy' in the first place?" There are a multitude of theories out there regarding what the cause of vampirism (or more specifically, the need to feed) really is. Some say it is caused by damaged chakras, a theory which would lend itself to the concept of the vampire's inability to keep the energy that their systems produce. Others say it is something akin to a scientific or medical malady created by man by way of a virus that has caused some sort of mutation on the basic DNA makeup of an otherwise completely normal individual. A virus which is currently only able to be treated through metaphysical means by way of feeding. Which of course, would cause one to wonder if perhaps someday there will be a medical answer...a "cure" for vampirism so to speak. Still others believe that vampires don't necessarily leak energy but instead just don't produce enough of it on their own to be able to maintain a healthy and happy life. There are even those that believe that feeding isn't needed to replenish a deficient energy system so much as simply being a tool. One which is used to achieve greater use and control of one's abilities and therefore eventually leading to the ascension of one's higher self.
However, no one really knows for sure why we are the way we are. I suspect this is because there actually isn't one universal answer that covers all of us. I say this because despite the many different theories available out there, most have one specific theory that seems to make more sense to them then the others. Even among those that haven't heard any the various theories, upon deep self reflection many find that they will pose a theory on their own. And it will, most times, be among one of the already proposed possibilities for the cause of vampirism.
My personal thoughts on the subject is that there isn't one cause, one reason. In my opinion, I think there are various causes. Perhaps, only when we look at each person on a case by case basis, will we be discover each person's individual reason for being of such a nature. In my case, I know that the cause of my own vampirism is due to none of the above theories. The reason I need to feed is that I use my energy up very quickly. I produce it just as well as any non-vampiric person. In fact I would actually hazard to guess that if there were a way to physically measure such a thing, one would find I might even produce energy within my personal stores faster then normal. However I still use it up too fast and this is not something I have control over. It just takes a great deal of energy to maintain many of my abilities. Empathy, telepathy, telekinesis, astral projection, energy work, healing and dream walking all take energy to maintain and/or accomplish. Because many of these abilities are not of the sort that I can easily switch on or off, i have no say in whether my energy get's used this way or not. The abilities are there to stay but they do cost me. Therefore vampirism is the only answer for me. Even if I went to a healer, they could not help me because it is not caused by some sort of damage that would benefit from a healers touch.
